MONTPELIER - The official overseeing the launch of Vermont's online health insurance marketplace says the system is on track for its scheduled opening.

Vermont Health Reformer Director Robin Lunge says there are likely to be some bumps on the way, but the system is ready to go live at 9 a.m. Tuesday. A call center will open at 8 a.m.

Tuesday is the official startup date for Vermont Health Connect, the state-sponsored health insurance marketplace being set up under the federal Patient Protection and Affordable Care Act. Coverage begins on Jan. 1.

Lunge says there were some technical problems over the weekend, but staff is working to ensure those aren't a problem on Tuesday.

She says officials don't expect many people will begin buying insurance until closer to Jan. 1.
